DC Power supply  

You will need to stabilise the voltage - there are converters available that will handle that for you at the expense of a few amps.

Cheerio,

RE: DC Power supply

What is the allowed voltage range?

Any idea for the connector name?

RE:

You might find more details at PSU datasheet https://deltapsu.com/en/products/adapter/ADT-150C24AC ( https://deltapsu.com/en/products/download/Datasheet/ADT-150C24AC)

The connector is a standard '4Pin Din'

and maybe something at https://github.com/prusa3d/Buddy-board-MINI-PCB

RE: DC Power supply

Thank you!

I've tried to follow the power on the schematics and I'm no expert but it looks like the 24V power is only sent to:

• LM25011MY which accepts 6-42V input
• TMC2209-LA which accepts 5-29V input
• The "HEATER" connector
• The "HEAT BED" connector
• The drain of MOSFETs that accept 40V max

Can I reasonably assume the heater and heat bed accept 22-29V? That would make the project feasible.

RE: DC Power supply

I guess the motor drivers also sends the same voltage to their motor, so the motors would have to accept this voltage range too. I could not find their specs, and on the specs of suggested replacements[1] I don't see any voltage mentioned. I'm not sure how this works for motors. Can I assume they will also accept 22-29V?

RE: DC Power supply

No idea.

But I know that PID controllers for heat bed and hot end have a defined min max values per given point in time, which means if you have not enough or too much power going into the component then it may trigger protection systems and abort the print process.
